I have Kezia in my database, although she's not connected to me, other than very peripherally - her daughter Maria Briars married into my Legate family from Henlow, Beds. Kezia married William James Briars at Stevenage, Herts on 24 Dec 1840. The marriage can be found on
www.freebmd.org.uk. in Hitchin registration district in the Dec quarter 1840 vol 6 page 914 - Kezia is indexed as Patenam. If you purchase the marriage certificate you'll get her father's name - this can be ordered online at
http://www.gro.gov.uk/gro/content/certificates/Langford baptisms for this period are on the IGI at
www.familysearch.org (at least female baptisms are), and there's no Kezia, but there is a Crisanna on 10 Oct 1813. Whether this is a mangling of Kezia I don't know, but I can't find any subsequent reference to Crisanna. You'd need to view the parish register microfilm, and possibly the Bishops Transcript too, to see what you think her name is - you can order and view them at your nearest LDS Family History Centre. But if it's definitely Crisanna it will be a job to prove that she was actually Kezia.
Got all excited for a moment when I found the family in 1871, living next door to Josiah and Maria Legate, where living with James and Kezia Briars was a William Norman 19 described as wife's brother. Kezia was 58 at this time, making it unlikely that William could have been a full brother, but checking him out I think he was the son son of Isaac Norman who married Rebecca Briars in 1839, so he appears to have been connected via the Briars, not the Patemans.
No doubt that your next step should be to purchase the marriage cert. If her father was John, the same as Crisanna's, then you can start to consider looking at the parish register to see if there's a possibility that the name has been mistranscribed on the IGI
